Goulds Pumps Pump NM 3196

Oil should be changed at least every 3 months (2000 hours) or more often if there are any adverse atmospheric conditions or other conditions which might contaminate or break down the oil. If it is cloudy or contaminated as seen by inspection through the sight glass, it should be changed immediately.

WARNING: Pumps are shipped without oil. Oil lubricated bearings must be lubricated at the job site.

Remove fill plug and add oil until level is at the center of the sight glass. Replace fill plug.

Change the oil after 200 hours for new bearings, thereafter every 2000 operating hours or 3 months (whichever comes first).

A high quality turbine oil with rust and oxidation inhibitors should be used. For the majority of operational conditions, bearing temperatures will run between 120°F (50°C) and 180°F (82°C). In this range, an oil of ISO viscosity grade 68 at 100°F (40°C) is recommended. If bearing temperatures exceed 180°F (82°C), use ISO viscosity grade 100 with Bearing Frame cooling or Finned Tube oil cooler.

Grease lubricated bearings are pre-lubricated at the factory. Most pumps have Sunoco 2EP grease.

High temperature units (pumpage temperature greater than 350° F) use Mobil SCH32. Regrease bearings every 2000 operating hours or 3 months.

• Check the foundation and the hold-down bolts for tightness.

• If the pump has been left idle, check the packing. Replace if required.

• Check the shaft alignment. Realign if required.

Warning: This procedure requires trained personnel with PPE!

• Check level and condition of oil through sight glass on bearing frame.

• Check for unusual noise, vibration and bearing temperatures.
